C
History:
C language was designed and developed by Dennis Richie at AT & T’s Bell laboratories situated at USA in the year 1972. It was created as a success of B-language. A language earlier development by Ken Thomson at Bell laboratories for P.D.P – 7 computer Dennis Ritchie developed from already existing languages such as algo, Bept, B that used the Unix Os.
C is often consider to be a middle level language since it possesses features of high level language i.e. it combines the best element high level language with control and flexibility of an assembly language. It is also known as a language.
C is case sensitive language.
Structure of C:
Solutions:
Eg.C.1. Write a program to input name, roll number.
# include
# include
void main ( )
{
int r;
char n[20];
clrscr ( );
printf (“Enter the roll number:”);
scanf (“%d”, &r );
printf (“Enter the name:”);
scanf (“%s”, &n );
printf (“%d”, r);
printf (“%s”, n);
getch ( );
}
Eg.C.2. Write a program to input the name, roll number, marks of three subject. Calculate total and average.
# include
# include
void main ( )
{
int r, m1, m2, m3, tot, avg;
char n[20];
clrscr ( );
printf (“Enter the roll number:”);
scanf (“%d”, &r);
printf (“Enter the name:”);
scanf (“%d”, &n);
printf (“Enter the marks1:”);
scanf (“%d”, &m1);
printf (“Enter the marks2”);
scanf (“%d”, &m2);
printf (“Enter the marks3”);
scanf (“%d”, &m3);
{
tot = m1 + m2 + m3;
avg = tot / 3;
}
printf (“%d”, r);
printf (“%s”, n);
printf (“%d”, m1);
printf (“%d”, m2);
printf (“%d”, m3);
printf (“%d”, tot);
printf (“%d”, avg);
getch ( );
}
Eg.C.3. Write a program to input book number, name, author name, price, number of copies. Calculate total.
# include
# include
void main ( )
{
int bno, p, noc, tot;
char bnam[20], anam[20];
clrscr ( );
printf (“Enter the book number:”);
scanf (“%d”, &bno);
printf (“Enter the book name:”);
scanf (“%s”, &bnam);
printf (“Enter the author name:”);
scanf (“%s”, &anam);
printf (“Enter the price:”);
scanf (“%d”, &p);
printf (“Enter the number of copies:”);
scanf (“%d”, &noc);
tot = noc *p;
printf (“%d”, bno);
printf (“%s”, bnam);
printf (“%s”, anam);
printf (“%d”, p);
printf (“%d”, noc);
printf (“%d”, tot);
getch ( );
}
Eg.C.4. Write a program to find area of a circle.
# include
# include
void main ( )
{
float a, r;
clrscr ( );
printf (“Enter the value of r:”);
scanf (“%f”, &r);
a = 3.14 * r * r;
printf (“\n Area: %f ”, a);
getch ( );
}
If – Statement:- The if-statement is a control statement that test a particular condition. Whenever, the evaluated condition comes out to be true, then that action or the set of actions are carried out. Otherwise the set of actions are ignored and statement II is executed.
Syntax:
if (expression)
statement (s); ……………….I
else
statement (s); ………………II
Nested if /else – statement:- In a program to specify several conditions and take one out of them called a nested if/else – statement.
Syntax:
if (condition I)
statement;
else if (condition II)
statement;
else if (condition III)
statement;
:
:
:
else
statement;
The conditions are evaluated from top to bottom and whenever the evaluated condition is true, the corresponding statements are executed and the rest of the statements are skipped. The arrangement of statements in this manner is called “ if/else, if-ladder ”.
Eg.C.5. Write a program to input gender and print good morning Sir and M’am.
# include
# include
# include
void main ( )
{
char a[20];
clrscr ( );
printf (“Enter your gender male/female:”);
scanf (“%s”, &a);
if (strcmp(a, “male”)==0)
{
Printf (“Good Morning Sir”);
}
else
printf (“Good Morning M’am”, );
getch ( );
}
